Window Balance 15HD BSI TB

Thanks for reaching out! Your balances appear to be our Series 751 Channel Balances. Given the lengths of your balances, you'll need the S751-19, S751-15, and the S751-23. Although, you may want to double check the length of each balance. You'll also need to confirm the stamps from each balance channel.

For example, the balance stamped with the 15HD, likely has a 16" channel. The 15" balance is stamped with a 14HD.
